Application filed February This invention relates to splasherjpietes for blast furnaces and more particularly to u novel mounting and operating mechanism for such plates, and has for one of its objects the provision of power n i'eiins for iinov inc; the splusher plate into sea out of posn tion. Another object is to provide a plate mounting which will maintain the platoon the furnace at all times, thereby preventing the'danger oi'the plateloeing dropped while being manipulated into position and endangering workmen.

A further objcct is to provide a splzisher plate and operating mechanism having the novel design, construction and combination of parts hereinafter described and illustratedin the accompanying drawings.

' In the drawings- Figure 1 is a front elevation of a portion of 2 blast furnace having my iiwention up plied thereto.

Figure 2 is a plan View showing my invention applied to a blast furnace. v.

Figure 3 is u partial side elevation of a blast furwce showing the splnshcr plate and iron runner in section Referring more particularly to the drawi'ngs, the numeral 2 designates the bosli wall of a standard blast furnace, the upper portion or stuck (not shown), of Which-is sup; ported on the furnace columns 3. The fur nace is provided with the usual iron tapping hole 4, and in front of-the tapping hole is a skimmer trough or runner 6, in which molten metal is conducted from the blast furnace to the skimmer, from which it flows int0 the iron runners leading from the dis charge end of the skimmer to the pouring.

spouts or, when used, to the pig beds.

The metal when tapped into the trough or runner 6 splashes anclpresents a turbulent flow, so that it is the practice to place a splash plate 8 over the furnace end of the trough 6 to prevent the metal splashing over the sides of the trough. Heretofor'e the splash plates 8 have been separate from the furnace andhave been'manually lifted onto and from the trough.

The splash plate 8 of the present invention is suspended from a rock'shaft 9 journaled iIi' bearings 10 secured on the furnace shell. The plate 8 has a pair of short angles 12 secured to its upper face to form supporting t 13. A pair of suspension levers 14; are

I 1;? which are apertured to receive a pivot of the :cylinder 21 wi 192?. serial are. 166,895.

keyed to the shaft ,9 and have their lower ends epertured to receive the bolt 13, the bolt 13-3 forming a pivotal eonnecti'on between the levels 14 and angle lugs 12. 1

A power lever 15 is keyed to the shaft 9 and has its free end connected by :1 clcvico 16 to a short length of chain 17, which'in turn is connected to one end of a cable 18, which is trained over suitable sheaves 19 and has its other cnd 'connected to the piston rod 20 of e fluid pressure cylinder 21., which may 1 be mounted on any suitable base such as the cast house column 2:2, as shown. v The splash plate 8 is shown in its lowered or operutiveposition in the drawings, end when it is desired to move the plate into inoperative position, it is only necessary to admit fluid under pressure to the cylinder 21 which will cause the piston rod 20 to move into the cylinder and thereby pull. on the cable 18 to raise the power lever 15. lYhen the lever 15 is raised the shaft 9 will be rocked to raise the levers 14 and splash plate 8.-

When it is desired to more the'splasher plate 8 into operative position, the operation 1 be reversed so as to? permit the plate 8 to be lowered into operative position by gravity.

It will be readily understood that manual labor in handling the splnsher plate 8 of this invention is entirely dispensed with, thereby facilitating the use of the plate and giving safety to the workmen.

lWhile I have shown and described one specific embodiment of my invention, it will be understood that I do notwish to he limited thereto since various modifications may he made Without departing from the scope i of my invention as defined in the appended claims.

1. The combination with a blast furnace, having the usual tapping holeend runner trough, ofa splasher plate pivotzilly supported'on said furnace for vertical movement and adapted tobe raised and lowered into and out ofsition over said trough adjacent'the tapping hole, and power means tor raisingand lowering said splasher plate.

2. The combination with a; blast furnace,

having the usual tapping hole and runner trough, of a splasher plat'e,'a shaft journsled on' said; furnace, means for rotating said shaft, and means connecting said splasher plate and said shaft whereby said plate may;

lie

be raised andlowered by rotation of said shaft.

3. The combination with a blast furnace, having the usual tapping hole and runner tron h, of a-shaft journaled on said furnace, asp asher plate secured to said shaft and adapted to be moved yertically into and out of position over said trough by the rotation of said shaft, and power means for rotating said shaft.

4c. The combination with a blast furnace, having the usual tapping. hole and runner trough, of a shaft journaled on said furnace,

a splasher plate secured'to said shaft and adapted to be moved vertically into and out of position over said trough by the rotation of said shaft, a lever secured to said shaft, a source of power, and a connecting element connecting said source of power and said lever for causing rotation of said shaft.

5. The combination with a blast furnace,

'having the usual tapping hole and runner trough, of a shaft journaled on said furnace, at splasher plate secured to said shaftand adapted to be moved vertically into and out of position over said trough by the rotation of said shaft, a lever secured to said shaft, 21 source of power. and a flexible coi'inec'ting element connecting said source of power and i said lever for causing rotation of said'shaft.

6. The combination with a blast furnace, having the usual tapping hole and runner trough, of a shaft journaled on said furnace, at splasher plate secured to said shaft and adapted to be moved vertically into and out maaees of position over said-trough by the -rotation of said shaft, a lever secured to said shaft,

a fluid pressure cylinder, and a connecting element connecting said cylinder and said lever for causlng' rotation of said shaft.

7. The combination with a blastfurnace,

having the usual tapping hole and runner trough, of a shaft journaled on said furnace, a splasher plate adapted tobe moved verti cally into and out of position over said trough, meansconneot-ing said late and said shaft whereby said plate will e raised and lowered by rotation of said shaft, a lever secured to said shaft, a fluid pressure cylinder, and -a,,connccting"eiemcnt connecting said fluid pressure cylinder and said lever.

,8. The combination'with a blast furnace, having the usual tapping hole ,runner trough, of a shaft journaled on said furnace,

a splasher plate adapted to be moved vertically into and out of position over said trough, levers pivotally connected to said splashc'r plate and keyed to said shaft Whereby said plate will be raised and lowered by rotation of said shaft, a second lever keyed to'said shaft, a fluid pressure cylinder, and a flexible connecting'member connecting said cylinder and said last named lever, whereby operation of said fluid pressure cylinder will rock' said last namedlever and rotate said shaft. v

y In witness whereof, I have hereunto signed my name.
